To all whom ittmay concern: v 1

Be i known that 1, CHARLES K. STINSON,

a citizen of the United States residing at ates in conjunction with coiled springs to produce resiliency, the objects of myv inven tion bein first, to provide an operative resilient ve icle tire without the use ofrubber as' the elastic factor, second, to adequately protect the springs employed from injury incident totheir use near the ground.

Other objects and advantages will be apparent from the following description.

This application is a continuation of myapplication for shock absorbing vehicle tires filed September 19, 1911 Serial Number 650,169, and referring to like subject matter.

I attain these objects in the manner illustrated in the accompanying drawings in which- Figure 1, is a vertical cross section through a motor vehicle wheel showing the construc-.

tion of the tire, the arrangement of its parts, and its action when striking the side of a wheel. Fig. 2, 1s a side view of a portion of the tire showing the circumferential arrangement of the springs. Fi 3, is a cross section of a modified orm .0 the tire.

Similar letters and figures refer to similar parts through out the several views.

With reference to the drawings A designates theinner rimof the tire and B a.

plurality of sets of coil springs "arranged circumferentially at or near its edges, and C a rigid floating guard rim wider thanthe inner rim and having a pair of channel'irons a secured around its inner periphery, to hold the outer ends of the coiled springs, said channel irons being spaced in from the edges of the guard rim a sufficient distance to secure protection for the coiled springs.

D 1s a narrow bufier secured to the inner eriphery of the guard rim and centrally.

Specification of Letters Patent.

Continuation of application Serial No. 650,169, filed September 19, 1911 11, 1914. Serial ND. $18,000.

an obstacle at Patented Sept. 1, 1914.

This application filed February the motion and preserving the springs from either crushingor over stretching.

The coiledsprings are arranged close together circum erentially and form elastic screens at each side of the tire sufficiently close to exclude objects that would otherwise enter between and injure the springs. The springs B are preferably secured to the innermost. sides of the channel irons 0 see cured to the outer or guard rim, and the opposite ends of said springs are secured to the outermost edges ofsimilar but oppositely disposed channel irons E secured adjacent the edges of and to the outer periphery of'the inner rim A, as clearly shown lIl Flg. 1. However, this structure whereby the springs are secured to the two rims may be modified or changed. For example, as shown in Fig. 3, I may secure the inner edges of the coil springs through openings a in the inner rim A, and secure the outer edges thereof through openings f in the auxiliary band F secured to' inner eriphery of the guardrimC. In this modification the buffer D is secured to the inner periphery of the auxiliary band F. A suitable tread H of any suitable material may be secured to the exterior of the guard rim 0. The springs B preferablyare normally of a length less than the normal distance between'theadjacent channel irons on the inner and outer rims, and in assembling the tire, one end of each spring'is secured to a channel iron on one rim and then stretched or ut under tension to bring its opposite end into posi tion to be secured to the channel iron on the same side of the other rim. In the modification shown in Fig. 3 the springs are likewise stretched into operative position, but the ends are secured in the openings in the band and'the inner rim and not into the openings in the channel irons, as in the modification shown in Figs. 1 and 2.

In operation, the springs are always under tension and support the load on the wheel axle by yieldingly suspendingthe axle from, the rigid outer or guard rim C. When an obstruction in the road is encountered, the outer rim will move eccentricall with regard to-the inner wheel and further stretch the springs B in the ripper portion of the wheel. The buffer D will contact with the inner rim when an excessive shock is encountered and prevent further eccentric movement of the inner or outer rims rela- 110 and outer rims, and a series of coiled springs arranged on each side of said bufier and con- 15 nected to the inner sidesof the channel members secured on the outer rim, and to the outer sides of the channel members secured on the inner rim.

In testimony whereof I aflix my signature 20 in presence of two witnesses.

CHARLES S TINSON.
